A Seven - month old female Kankrej calf was presented to Large Animal Clinics - Out-Patient - Medicine Unit of Madras Veterinary College Teaching Hospital, Chennai, with the history of recurrent tympany for two months with scanty dung with a pasty consistency. Onclinical examination of the animal, bilateral distension of the abdomen was noticed. Haematobiochemistry revealed neutrophilia with leucocytosis and significantly elevated Gamma-Glutamyl-Transferase values. In radiography, no change in the silhouette of reticulum could be appreciated other than a mild bronchial pattern. Ultrasonography revealed an anechoic encapsulated cavity with echogenic internal spots of the reticular wall. Based on these findings, the calf was diagnosed with an abscess in the reticulum. Accordingly, the abscess was drained and the animal was treated with antibiotics and supportive therapy and the animal recovered uneventfully.

In present day, supplementation of extra minerals and vitamins is highly essential in commercial diets due to high productivity and to withstand the detrimental effects of different stresses. Selenium is one of essential trace minerals for better growth and productivity as well as anti-stressor in commercial broilers. Nano-selenium can effectively be synthesized through High Energy Ball Milling (HEBM) technique from its precursor, for use in commercial broilers as anti-stressor and to support multiple bodily functions. The prepared nano particle had 44.5 % of selenium as measured by Energy Dispersive X-ray (EDAX) analysis with the product yield of 50 g/hr. The chemical composition of sodium selenite powder was same as that of the original mega particle. The size of Se nano particle ranged from 37-85 nm as analyzed through Field Emission Scanning Electron Microscope (FESEM). X-Ray diffraction pattern confirmed that the synthesized Se nano particle was free of impurities and provided accurate information on the atomic arrangements. The Fourier Transform Infra-Red (FTIR) spectrum of synthesized nano particle source of selenium peaks was located at 3023.26, 2800.12, 2502.23, 2314.17, 1610.40 and 1413.30 cm-1 which showed chemical bonding in a target material. The zeta potential of nano selenium was -23.30 mV when analyzed through particle size analyzer. Se nano-particles could be successfully synthesized through High Energy Ball Milling method from its precursor and could be characterized for its quantity, size, shape, stability and purity. The synthesized Se nano-particles could be utilized for the conduct of biological trial in commercial broilers.

Administration of higher dosage of chlorine leads to a concern about proper dosage determination for shrimp hatchery operations. Hence, the dosage application needs to be reworked at the present context. Accordingly a Completely randomized design experiment with 6 treatments (control, 10 ppm, 20 ppm, 30 ppm, 40 ppm, 50 ppm of active chlorine content) with 3 replications was conducted. The water quality and the bacterial load were monitored once in 3 hours continuously. The salient observations of the study was that the exposure time for residual chlorine to be nil for the tank with chlorination of 10 ppm concentration was 6 hours, for 20 ppm and 30 ppm it was 18 hours and for 40 ppm and 50 ppm it was 21 hours. Also the results shows that bacterial load was nil in all the treatments viz. 10 to 50 ppm. The pH of the water gets increased and then stabilized. It could be concluded from the study that the chlorination is required in shrimp hatcheries. But the optimum dosage is 10 ppm for ensuring better water quality in shrimp hatchery which is very much less when compared to the general dose of upto 30 ppm for other purposes. Another experimental trial with three replications was conducted to ascertain the survival of post larvae of P. monodon from PL5 to PL 20 with the 10 ppm active chlorine. The study showed that survival was high in 10 ppm.

Indigenous duck breed of Assam are popular with considerable production potential with minimal input and mostly reared under semi intensive system of management. These ducks are maintained in all agro climatic zones of Assam and different from other indigenous duck genetic resources available in the country. But the genetic structure of these duck varieties was not fully studied; hence the genetic characterization of Assam ducks was assessed with 23 FAO recommended duck specific microsatellite markers using advanced automated genotyping technique. The analysis revealed that totally 91alleles were observed with the number ranging from 1 (CAUD025) to 7 (CAUD004 and APH009) and an overall mean of 3.957 ± 0.32 across the loci. The mean observed and expected heterozygosities were 0.4444 and 0.5113. All the microsatellite loci were found to be highly polymorphic except CAUD025. In Assam ducks, PIC value ranged from 0.14 (APH001) to 0.71 (CAUD004) with a mean value of 0. 4813. Nearly 14 out of 23 loci had PIC values of more than 0.5 indicating that these markers can be effectively used for genetic diversity analysis. The Chi-square test revealed that among the 23 microsatellite studied, only 12 were in Hardy-Weinberg equilibrium proportions and the rest departed from equilibrium. Selection and non-random mating could be the main reasons for this disequilibrium. The markers used in the study were found to be highly informative, explores high genetic variation in the population which could be exploited for their improvement.

A biological experiment was conducted to study the effect of different mating ratio on fertility and hatchability of TANUVAS Namakkal quail-1 breeders. The experiment was conducted by using two hundred and fifty adult birds of the age 15-25 weeks (males:25 and females:125) and 35-45 weeks (males:25 and females:125) TANUVAS Namakkal quail-1 breeders. The different male: female ratios viz. T1 (1:2), T2 (1:3), T3 (1:4), T4 (1:5) and T5 (1:6) were maintained in cages separately. All the birds were reared as per the standard management procedure and fed with Japanese quail breeder diet. The fertile eggs were collected from each male: female ratio separately for 28 days period. Eggs were set in the incubator and per cent hatchability, infertile, embryonic mortality and dead-in-shell were studied. The results of the experiment revealed that the hatchability was highly significant (P<0.01) in T3 group (77.62%) with a mating ratio of 1:4 in 15 to 25 weeks age group and in T2 group (72.83%) with a mating ratio of 1:3 in 35 to 45 weeks age group. From this study it could be concluded that the optimum mating ratio for “TANUVAS NAMAKKAL Quail-1” breeder for younger age group is 1:4 and for older age group is 1:3.

2022
R, Richard Churchil
The genetically improved modern commercial layers are capable of producing 330 eggs in their productive life of up to 72 weeks. The journey of genetic improvement continues and the breeding companies now developed ‘long life’ layers that can lay 500 eggs in 100 weeks of age. The changing production dynamics of layer chicken calls for better understanding of nutrient requirements and good nutritional programming. Prediction models are being used to assess the nutrient requirements of the hybrid layers; while, precision feeding of quantity of feed and or nutrients can lower feed costs and ensures more predictable bird performance. In-ovo and early chick nutrition give jump start at juvenile stage of chicken. The idea of split feeding, although beneficial in certain production parameters, suffers the disadvantages of additional infrastructure and workforce requirements. The nutritional programme foregg size, shell quality and feeding for value added designer egg production is aimed at increasing the profit to the farmers. In recent days, feeding for healthy gut that enables efficient digestion and absorption of nutrients has also gained paramount importance. The concept of feed nanotechnology can help in increasing nutrient availability and environment protection; while, phytogenic products can some extent replace the role played by antibiotic growth promoters. The advancements in biotechnology has opened up not only numerous opportunities for the development of products and technologies for poultry feeding, but also to study the influence of nutritional factors on genomics, proteomics and metabolomics.

Palanivel, M | S.V. , Rama Rao
‘New generation’ Dried Distillers’ Grains with Solubles (DDGS) collected from modern ethanol plants were analysed for its nutritional composition and included in the diet to assess the performance of commercial Vanaraja chickens. Six numbers of commercial ‘new generation’ DDGS samples collected from modern ethanol plants were analyzed for their basic nutrient composition and amino acid profile. Five isocaloric and isonitrogenous experimental diets containing graded levels of ‘new generation’ DDGS (0, 2.5, 5.0, 7.5 and 10% DDGS) were formulated as per ICAR-DPR standards for Vanaraja chickens basis, and fed for chicks (9 replicate pens containing 6 chicks each) of commercial dual purpose birds of Vanaraja strain for the period of 6 weeks. Growth performance of birds was recorded at 7, 14, 21, 35 and 42 days of age and 9 representative birds per treatment (one each from replicate pen) were randomly selected and processed to study their carcass yield and characteristics. The ME and CP content of ‘new generation’ DDGS is 2850±57 Kcal/Kg and 27.35±1.16%, respectively. There was no significant (P>0.05) difference in the growth performance of birds during chick stage (7 to 21 days) and during early finishing stage (35 days) birds fed diets containing ≥5.0% ‘new generation’ DDGS had shown lower weight gain and significantly (P<0.05) poor feed conversion compared to Control. There was no significant difference in the carcass yield and its characteristics between the dietary treatments. Good quality protein rich ‘new generation’ DDGS can be used (10%) in the diets fed to commercial Vanaraja chickens without significant impact on overall performance of birds.
